Paper Abstract
The constant modulus algorithm (CMA) has low computational complexity while presenting slow convergence and possible
convergence to local minima, the CMA family of algorithms based on affine projection version (AP-CMA) alleviates the speed
limitations of the CMA. However, the computational complexity has been a weak point in the implementation of AP-CMA. To reduce
the computational complexity of the adaptive filtering algorithm, a new AP-CMA algorithm based on set membership (SM-AP-CMA)
is proposed. The new algorithm combines a bounded error specification on the adaptive filter with the concept of data-reusing.
Simulations confirmed that the convergence rate of the proposed algorithm is significantly faster; meanwhile, the excess mean square
error can be maintained in a relatively low level and a substantial reduction in the number of updates when compared with its
conventional counterpart.
